Q91. Which QoS mechanism uses PHBs?
Q92. A company uses site-to-site IPsec VPN tunnels established over the public internet as a backup to its private WAN. The interoffice IP telephony service quality is degraded when a failover event occurs. What known design limitation can cause this issue?
A. maximum headend router throughput
B. circuit bandwidth
C. transport reliability
D. number of remote sites
Q93. When a Cisco ASA adaptive security appliance is configured for active/standby failover, which MAC address is used for the active unit?
A. the MAC address of the primary unit
B. the MAC address of the secondary unit
C. the virtual MAC address
D. the standby MAC address
Q94. Which statement is the most accurate regarding IPsec VPN design for an Enterprise Campus environment?
A. VPN device IP addressing must align with the existing Campus addressing scheme.
B. The choice of a hub-and-spoke or meshed topology ultimately depends on the number of remotes.
C. Sizing and selection of the IPsec VPN headend devices is most affected by the throughput bandwidth requirements for the remote offices and home worker
D. Scaling considerations such as headend configuration, routing protocol choice, and topology have the broadest impact on the design.
Q95. Refer to the exhibit. Based on the configuration, why are routers R1 and R2 not exchanging OSPF routes?
A. The OSPF process numbers are different.
B. There is no backbone area configured.
C. The router IDs are different.
D. OSPF is not enabled on the interfaces.
Q96. Which command can you enter to inject BGP routes into an IGP?
A. redistribute bgp
B. redistribute static
C. redistribute static subnet
D. default-information originate
Q97. Which option maximizes EIGRP scalability?
A. route redistribution
B. route redundancy
C. route filtering
D. route summarization
Q98. Refer to the exhibit. A customer requires a web application implementation, but the web server has communication only to the application server and users, and the database server has communication only to the application server. What firewall design is the best fit for this scenario?
A. transparent mode with the servers on the same subnet
B. routed mode with three security zones
C. transparent mode with three security zones
D. routed mode with two security zones
Q99. Which two design recommendations are most appropriate when EIGRP is the data center core routing protocol? (Choose two.)
A. Summarize data center subnets.
B. Advertise a default route into the data center core from the aggregation layer.
C. Tune the EIGRP timers to enable EIGRP to achieve quicker convergence.
D. Adjust the default bandwidth value to ensure proper bandwidth on all links.
Q100. Which two options are VRF components. (Choose two.)
